The non - isothermal crystallization behavior and crystal structure of poly(vinylidene fluoride)(PVDF)/poly (methyl methacrylate)(PMMA)blends were investigated at different cooling rates using differential scanning calorimeter and X-ray diffractometer, and their non-isothermal crystal...

SEM, TEM, XRD and other methods were used to analyze their morphology, crystal structure and distribution, and UV-Vis spectroscopy, Raman spectroscopy and other technologies were used to characterize their optical properties and surface-enhanced Raman scattering effect. The results show that the nano...

The effects ofmethyl groupin 3 methyl 4 nitropyridine N oxide (POM) on the second order nonlinear optical properties and the crystal structure were studied,and a semiempirical analysis on the electronic and microscopic properties was carried out. ...
To this end, the structure and the dynamics of this particular phase is varied by blending with PMMA and by suitable annealing. It will be shown that the electric efficiency is governed to a large extent by the type, the number, the mobility, and the properties of trapping sites of ...
Blends of PVF2 with poly(methyl methacrylate) (PMMA) are known to be compatible in the amorphous state [1-9], with multiple crystal forms of PVF 2 appearing in the blends when they are crystallized [10, 111. Previously [12], utilized a special film drawing technique adopted from Petermann...
SEM micrographs show spherulitic crystal structure of PVDF; the size of the spherulites is about 18 . These spherulites become gradually less distinct as the concentration of PMMA increases in the polyblend samples. A small hump is observed in the dielectric loss thermograms of the polyblends ...
